Title: Drying detector
Inventor: KONNO SETSUZOU
IPC: G01N27/04
Filed: 1983-02-28
Abstract: PURPOSE:To decide on the drying state of a body to be dried securely by adding a smoothing part consisting of a capacitor. CONSTITUTION:An electric signal obtained by a conversion part B is smoothed by the smoothing part C consisting of the capacitor 6. The switch part D consisting of a diode 7, resistance 8, etc., is operated by the level of the electric signal smoothed by the smoothing part C to detect the degree of drying. Thus, the smoothing part C is added to discriminate clearly between the wet and dry states of the body to be dried so that the body is dry when the signal level is high and wet when low. Consequently, the decision on the drying state of the body to be dried is made securely.

Title: Protective relay for transformer
Inventor: TAKAHASHI YOSHITAKA
IPC: H02H7/045
Filed: 1993-02-23
Abstract: PURPOSE:To prevent erroneous function due to exciting rush current when the transformer voltage is recovered after removal of primary system fault by detecting the fault on the primary of a system by means of an undervoltage element, a differential current detecting element, and a coordination timer and locking the erroneous function of the differential current detecting element upon recovery from the fault. CONSTITUTION:When OR outputs of respective phases from differential current detecting elements 1a, 1b, 1c lag behind the output from an ON-delay timer 4 for an undervoltage element 2, a decision is made that a fault occurred on a primary system and the time of an OFF-delay timer 7 and the outputs from the differential current detecting elements are locked. When the function of the differential current detecting elements 1a, 1b, 1c leads ahead of the output from ON-delay timer 4, the time of the OFE-delay timer 7 and the outputs from the differential current detecting elements are not locked. The coordination ON-delay timer 4 is set at a time t1 > functioning time of differential current detecting element-functioning time of undervoltage element + a margin, which is about 50ms. The OFF-delay timer 7 is set at a time t2 which is equal to the duration of the differential current detecting element at the time of throw-in of transformer + a margin.

Title: Sound data interpolation circuit
Inventor: ISHIBASHI HIDEKI
IPC: G11B20/18
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To reduce the frequency of interpolation as much as possible by providing a means for selecting interpolation data only when pseudo error data is not included within a specified limit range. SOLUTION: A interpolation circuit 11 calculates interpolation data for pseudo error data determined to be an error at the time of data reading based on normal sound data before and after this. A data selecting circuit 12 determines whether pseudo error data in a buffer circuit 10 is included within a specified limit range set by using sound date before and after this as a reference or not. When the pseudo error data is included within the limit range, the pseudo error data is selected and when the data is not included within the limit range, its interpolation data is selected. Thus, since interpolation is not necessary when the pseudo error data is normal sound data, the frequency of interpolation is reduced as much as possible. Thus, the distortion of sound data caused by interpolation is reduced and a high sound quality is provided.

Filed: 1979-03-19
Abstract: PURPOSE:To prevent a wire from being stepwisely cut by forming a high purity aluminum layer on an aluminum alloy film, then dry etching a wiring pattern and forming a tapered wiring layer at the side surfaces. CONSTITUTION:A predetermined region is formed, and a silicon dioxide film 2 is coated on the surface of a semiconductor substrate 1. 1mum of aluminum alloy film 3 containing 0.5% of copper is coated on the substrate 1, and 0.2mum of high purity aluminum film 4 is formed on the film 3.

Abstract: PURPOSE: To improve the partial load characteristic for the centrifugal fluid machine, by rotatably providing a guide vane, eccentrically installing the guide vane to a position adjusting disk and allowing its rotary center to be also changed simultaneously.  
     CONSTITUTION: The turning operation of a crank 9b rotates a gear 5d causing a gear 8 to be rotated further rotating a gear 5b arranged on the same circumference. Accordingly, a gear 5a and a support axis 6a are rotated at a time turning a guide vane 4 fixed onto the support axis 6a. And if a crank 9a fixed to a support axis 6b is rotated,a gear 5c, that is, the support axis 6b and a position adjusting disk 7 are rotated all together. As understood by the above described, a support axis of the guide vane and the position adjusting disk can be independently rotated within a certain range and this operation causes an inlet angle and inlet radial position of the guide vane to be independently changed.
